Title:
  rebuild to same host with different image shouldn't check with
  placement

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) pike series:

Bug description:
  When doing a rebuild-to-same-host but with a different image, all we
  really want to do is ensure that the image properties for the new
  image are still valid for the current host.  Accordingly we need to go
  through the scheduler (to run the image-related filters) but we don't
  want to do anything related to resource consumption.

  Currently the scheduler will contact placement to get a pre-filtered
  list of compute nodes with sufficient free resources for the instance
  in question.  If the instance is on a compute node that is close to
  full, this may result in the current compute node being filtered out
  of the list, which will result in a noValidHost exception.

  Ideally, in the case where we are doing a rebuild-to-same-host we
  would simply retrieve the information for the current compute node
  from the DB instead of from placement, and then run the image-related
  scheduler filters.
